This paper "Long Term Investigation of Urethane Conformal Coating Against Tin Whisker Growth" was presented by Lyudmyla Panashchenko of NASA GSFC at the IPC Tin Whisker Conference, in December 2010. It describes the results of 11 years of aging of a conformal coat and its ability to inhibit tin whisker growth. It shows that whiskers continue to grow with time and how they may be constrained by the coating or how they may penetrate the coating depending on its thickness. This presentation includes the synchronized slides and audio. 32 minutes. Released 2011.
